The constantly changing pixel formats look suspicious. Is there a pv somewhere that will switch the camera into big endian mode? Maybe you could try setting the GETFEATURES pv to Off and see if that improves things? I don't have a Basler camera here to test unfortunately so I can't try any of these things...

Thanks,
Tom Cobb
